gen VI 502/502

Hi guys, I am thinking of replacing my built 454 (400hp) with a new gen VI 502/502, Boat is a 79 cigarette 20, motor is a new GM crate motor, full roller with alum heads. Just wondering what kind of problems I am looking forward to. Any help would be greatly appreciated. Thanks.

Is the "crate" engine designed for automotive use? If so, you will need to install inconel exaust valves and a cam with a wider lobe separation angle (114 or so)

Search for the threads on 572 crate motors, just about every thing should apply the same
